The distribution of marine debris and microplastic in Tidung Kecil Island, Jakarta Bay and Sembilang National Park, Palembang
AI summary Read the abstract
This study surveyed the distribution of marine debris and microplastics in the waters and sediments around Tidung Kecil Island in Jakarta Bay, Indonesia. The findings highlight the role of coastal communities and tourism in contributing to local microplastic contamination.
Abstract Plastic waste is one of the marine debris that has negative impacts on the marine environment, such as the death of biota and disturbing the beauty of nature. Plastics can degrade into microplastics. Microplastics in the marine environment can be found in waters and sediments, so they can enter the biota through the food chain. The research aims to examine the distribution of marine debris and microplastics on small islands (Tidung Kecil, Jakarta Bay) and the mainland (Sembilang National Park, South Sumatra). The total marine debris on Tidung Kecil Island (4.04 kg/m 2 ) was greater than that of Sembilang National Plants (0.71 kg/m 2 ). The average abundance of microplastics in the larger size area is greater than in small islands. This is because the substrate is predominantly clayey and muddy with a relatively calm environment, while on small islands the substrate is sand with a dynamic environment. The amount of marine debris found did not correlate with the abundance of microplastics.

AI summary Read the abstract
This Indonesian-language study identified and characterized microplastics in bottom sediments around Untung Jawa Island in Jakarta Bay. Multiple microplastic types were found, with particle distribution patterns related to local ocean currents. The findings document microplastic contamination in the sediments of an Indonesian island in the heavily polluted Jakarta Bay.
Microplastic Contamination Around Coral Reefs Diving Spot in Tidung Island, Kepulauan Seribu, Jakarta
AI summary Read the abstract
This study measured microplastic contamination in sediments at coral reef dive sites on Tidung Island in Jakarta Bay, Indonesia, finding 60 to 340 particles per kilogram. Fibers were the dominant type at all stations, and microplastic abundance may affect coral health in these tourism-dependent ecosystems.
Abundance and characterization of microplastic pollution in the wildlife reserve, Ramsar site, recreational areas, and national park in northern Jakarta and Kepulauan Seribu, Indonesia
AI summary Read the abstract
This is the first study to measure microplastic pollution in sediments across protected areas near Jakarta, Indonesia, including a wildlife reserve, a Ramsar wetland site, and a marine national park. Microplastics were found at all locations, with higher concentrations closer to human activity and during the dry season. The results suggest that even designated conservation areas are not spared from microplastic contamination.
Abundance of Microplastics in Mangrove Sediments on Pari Island, Jakarta Bay, Indonesia
AI summary Read the abstract
Researchers sampled mangrove sediments on Pari Island in Jakarta Bay in two seasons and identified microplastics by shape, color, size, and polymer type, finding that seasonal variation affected abundance and distribution. The study documents microplastic accumulation in a mangrove ecosystem adjacent to the Indonesian capital.
